Fright to the Finish (1954)
Olive is reading ghost stories to the boys. Popeye scoffs; Bluto decides to take advantage of this by staging various pranks (a headless man, an animated skeleton, and a sheet-over-balloon ghost). He pins the blame on Popeye and then goes to comfort Olive. Popeye retaliates by turning invisible, thanks to a jar of vanishing cream.
